Dieter, the problem is not so much in parsing the DAEMONS array, as it is
the fact that in puppet the services are configured from a different logical
perspective, rather than configuring what services are to start, you define
services individually and then "realize" certain services
for certain servers, this makes it hard to implicitly define the daemons

On the other hand, if require statements could be used to determine the
order of the services in the daemons array, then the order would still be
explicitly determined by the admin.

I mentioned the idea of having an index => param, maybe we could have a
before => Service['foo'],


before => foo,

to specify that the service should run before the other service.

of course the require statement could still fulfill that.
